[11.] "Snowdon was a name given by the Saxons to that mountainous tract which the Welsh themselves call Craigian-eryri: it included all the highlands of Caernarvonshire and Merionethshire, as far east as the river Conway. R. Hygden, speaking of the castle of Conway, built by King Edward the First, says: 'Ad ortum amnis Conway ad clivum montis Erery;' and Matthew of Westminster (ad ann. 1283), 'Apud Aberconway ad pedes montis Snowdoniae fecit erigi castrum forte'" (Gray).

It was in the spring of 1283 that English troops at last forced their way among the defiles of Snowdon. Llewellyn had preserved those passes and heights intact until his death in the preceding December. The surrender of Dolbadern in the April following that dispiriting event opened a way for the invader; and William de Beauchamp, Earl of Warwick, at once advanced by it (Hales).

The epithet shaggy is highly appropriate, as Leland (Itin.) says that great woods clothed the mountain in his time. Cf. Dyer, Ruins of Rome:

"as Britannia's oaks
On Merlin's mount, or Snowdon's rugged sides,
Stand in the clouds."

See also Lycidas, 54: "Nor on the shaggy top of Mona high;" and P. L. vi. 645: "the shaggy tops."

[13.] Stout Gloster. "Gilbert de Clare, surnamed the Red, Earl of Gloucester and Hereford, son-in-law to King Edward" (Gray). He had, in 1282, conducted the war in South Wales; and after overthrowing the enemy near Llandeilo Fawr, had reinforced the king in the northwest.

[14.] Mortimer. "Edmond de Mortimer, Lord of Wigmore" (Gray). It was by one of his knights, named Adam de Francton, that Llewellyn, not at first known to be he, was slain near Pont Orewyn (Hales).

On quivering lance, cf. Virgil, Æn. xii. 94: "hastam quassatque trementem."
